Chiesa di Santa Maria del Mercato o Oldofredi

Santa Maria del Mercato stands among Iseo’s historic houses near the market square. Commissioned in the fourteenth century by Giacomo Oldofredi for himself and his townspeople, it keeps a nursing Madonna, two Saint Georges, a Passion cycle and a luminous Perdon d'Assisi of 1727 — a devotional layer cake behind a modest eighteenth-century face.

Why it matters

The church was founded by the Oldofredi family and reflects the devotional life of Iseo. Its very names tell the story: "degli Oldofredi" for the feudal lords who built and owned it, "del Mercato" for the square it faces, the town’s historic trading square. Giacomo Oldofredi commissioned it in the fourteenth century on land already occupied by earlier family structures. Franciscan friars from the convent of San Francesco served its altars from the fourteenth century until the late seventeenth century. Its art and architecture reflect medieval, Franciscan and later Baroque phases.

What to notice

The church stands near Piazza Garibaldi, fitted into the street pattern: an irregular, trapezoidal body with a slanted front, its eighteenth-century facade only slightly wider than the portal, crowned by a window and a graceful curvilinear tympanum. Inside, the quadrangular presbytery is separated from the trapezoidal aisle by a wrought-iron gate. The altarpiece is a late fifteenth-century fresco of the Virgin nursing the Child, set in a Baroque frame surmounted by a wooden group of God the Father with the Annunciation. The oldest surviving works include private devotional paintings of the fifteenth to mid-sixteenth centuries, partly uncovered when later plaster came away, including two panels of Saint George killing the dragon and freeing the princess. On the nave vault, a polylobed stucco medallion holds the Perdon d'Assisi of 1727 — Francis interceding for the souls of Purgatory beside the allegorical Church with her cross and chalice — while the presbytery dome fills with the Assumption and coronation of the Virgin, and the Passion cycle around them is attributed to the Iseo-born painter Domenico Voltolini.

Context and history

The eighteenth century refashioned the interior: roofs were rebuilt and pilasters set against the walls, covering and partly destroying the older images. Later removal of that plaster brought the medieval devotional pieces back to light, and the interior retains visible layers of fresco. The Voltolini attribution belongs to this mature phase, some scenes transferred to canvas, others still fixed to the walls and vaults. The Franciscan connection ran deep: from the fourteenth century until the late 1600s the friars of the convent — now the town hospital — officiated here, and the 1727 Perdon d’Assisi reflects the continuing importance of the Portiuncula devotion after their departure. The building remains a chapel within the parish unit of Iseo.
